Purpose :
To compare short-term visual and anatomical outcomes of two distinct techniques of scleral fixation of intraocular lenses (IOLs).

Methods :
An interventional, retrospective, comparative case series of 15 eyes with aphakia after cataract extraction or trauma who had scleral-fixated IOL surgery from November 2015 to November 2016 was performed. All patients had surgery in a tertiary referral center in the Dominican Republic with at least 3 months of follow-up. The images were captured using an anterior segment optic coherence tomography (Visante, Carl Zeiss Meditec, Dublin, California, USA). Tilt and decentration measurements were performed with the Image J software. The 3 Point Region of Interest plug-in was used to delineate the anterior and posterior surfaces of the lens. The main outcome measures were the IOL decentration, tilting and the best-corrected visual acuity (BCVA).

Results :
A total of 15 cases were analyzed with a mean follow-up of 12.6 ± 18.99 months. Decentration and inclination in the sutureless scleral fixated (n= 11) and sutured scleral fixated (n=4) were (494 microns ± 710 vs. 328 microns ± 2.4, p = 0.514) and (2.9°± 2.7 vs. 2.23° ± 2.5, p = 0.660), respectively. As for visual acuity, the sutureless scleral fixated group had a BCVA of 0.44 logMAR and the sutured scleral fixated group was 0.43 logMAR (p = 0.918). Complications were reported only in the sutureless scleral fixated IOL being cystoid macular edema the most common complication (n=3).

Conclusions :
Our short-term results demonstrate that sutured fixated IOL had less position changes. Both sutured and sutureless techniques resulted in good visual outcomes.
